전역 광소멸법을 이용한 확산화염 내 그을음 입자의 농도 측정에 관한 연구

Abstract

In the present study, non-intrusive technique for the concentration measurements of soot particles formed within the flames was experimentally investigated. As part of this study, the full-field light extinction apparatus that enables us to obtain the spatial distribution of soot particle concentration within the flames was developed and implemented. In addition, the 3 point abel deconvolution algorithm was coded using a Fortran software to determine the spatial distribution and concentration of soot particles. The abel inversion analysis clearly indicates that the spatial distribution of soot particles within the flame can be faithfully reconstructed from the projected light extinction image captured by a CCD camera.
